MVR, an abbreviation for mechanical vapor recompression, represents a groundbreaking energy-saving technology that ingeniously reduces the dependence on external energy resources. It achieves this by ingeniously reusing the secondary steam energy it produces. The core principle behind this technology involves compressing the secondary steam, which is generated by the evaporator, using a steam compressor renowned for its high energy efficiency. This process transforms electrical energy into thermal energy, resulting in an increase in both pressure and temperature of the secondary steam. Subsequently, the elevated temperature of the secondary steam is channeled back to the evaporator, where it efficiently heats the materials, promoting further evaporation. This cycle effectively enables the recycling of the latent heat of vaporization of the secondary steam, resulting in significant energy conservation.
The DM series Single-stage geared steam compressor is an engineering marvel that primarily encompasses a compressor body, coupling, gearbox, lubrication system, motor, electronic instrumentation, and an advanced anti-surge control system. This remarkable piece of equipment boasts a compact design, ensuring ease of handling and maintenance, making it a practical choice for diverse applications.
3.3.1 To ensure a seamless installation, the Split Base Compressor with Frequency Conversion and Adjustable Speed should be placed integrally on the foundation. Enhance stability by placing wedge-shaped shims beneath the base, which are instrumental in achieving unit leveling.
Strategically position two wedge-shaped irons in an alternating format. Post leveling, secure these irons with spot welds at approximately 4 to 5 distinct points, ensuring meticulous craftsmanship.
These wedges should be precisely manufactured and installed by the user, tailored to specific conditions. A flawless contact surface is paramount, ensuring even contact on inclined planes.
It is crucial that the bearing capacity of the wedge iron does not exceed a robust threshold of 40Kg/cm2).
3.3.2 Employ a precision level to ascertain exactitude. Our leveling criteria demand remarkable precision: an axial level of 0.05/1000mm and a horizontal level of 0.10/1000mm.
These stringent standards guarantee precision and functionality.
3.3.3 Achieve coupling perfection by centering. Before initiating alignment, ensure compliance with the following prerequisites:
1) Deactivate the primary power supply for safety assurance;
2) Detach the protective coupling shield;
3) Carefully remove the diaphragm coupling intermediate section;
4) Inspect the motor installation plane for absolute flatness, free of any extraneous materials or dirt.
The bolt hole of the motor must exceed the bolt size, facilitating ease of adjustment through bolt loosening.
Prepare and utilize an adequate number of stainless steel gaskets to fully support the motor's foot. These gaskets must be flat and free from any attachments to ensure precision adjustments.
A dial indicator or a laser alignment meter, boasting an accuracy of 0.01mm, is essential and should be provided by the customer.
Equip yourself with a sturdy bracket as illustrated to support the dial indicator effectively.
For optimal alignment, mount a bracket on the motor wheel hub to accommodate a dial indicator, ensuring the probe rests on the compressor wheel hub's outer edge.
Adjust the motor feet bolts with precision to align the compressor and motor center lines. The outer circle's maximum deviation must not exceed 0.05mm, while the motor shaft center line should slightly surpass the compressor's low-speed shaft center line. Maintain a coupling end face deviation between 0.03~0.05mm.
Upon concluding these adjustments, secure the motor foot bolts firmly and meticulously review the coupling's outer circle runout and end face runout for precision.;
Ultimately, reinstall the coupling's intermediate section post the motor's idle testing phase.
3.3.4 Upon achieving optimal 'levelness' and alignment of the casing, anchor the bolts securely. Post mechanical or trial operations, it is wise to loosen and re-tighten the bolts for enduring stability.
3.3.5 The impeller is a high-speed marvel, vulnerable to solid or liquid intrusions that could inflict irreversible damage. Hence, ensuring the purity of the inlet and outlet pipelines adhering to system steam corrosion standards is indispensable. Non-compliant pipelines necessitate rectification.Incorporating solid-liquid separation equipment, such as a gas scrubber or sedimentation tee, ahead of the compressor's inlet straight pipe is strongly advised for enhanced protection and performance.
3.3.6 Proceed to install the compressor's inlet and outlet pipes. The installation must adhere to the PI diagram specifications, with accompanying pipeline accessories. Ensure that the connected pipeline is independently supported by a separate bracket, avoiding any undue stress on the compressor body itself.
3.3.7 Upon the successful installation of the main fan and its supportive ancillary equipment, and once the concrete has fully solidified, you are ready to proceed with the all-important compressor operation test. This crucial phase ensures that your Split Base Compressor with Frequency Conversion and Adjustable Speed is functioning optimally, setting the stage for superior performance and reliability.
3.3.8 Ensure that the electric control cabinet for the compressor is strategically positioned within a 5-meter radius of the compressor for maximum efficiency. The connection between the compressor and the electric control cabinet should be meticulously organized using pipe threading, discreetly installed underground for an uncluttered aesthetic. After positioning the electric control cabinet, expertly connect the wiring terminals within it to the network at the remote DCS, ensuring seamless communication and control.
